I did some improvement based on issue i faced during the assembly and tweaks to my liking
- added cavity at the middle lower floor so i could hide my tiny D8 receiver and lipo beneath
- i made it a snowcat with rear bed instead of rear cab
- reduced the hexagon hole from 6mm to 5.7mm because it was rotating inside
- added cover behind the dash
- modified the sprocket to mount on servo horn
- added a printable bearing in case you can't find one

The Track is the Lego 3873, total 60pcs.
You may notice in the pics where one has foam pads, another doesn't.
